Larger magnetic and appear to be better quality. This one is a little bass-ier, probably because there is no whizzer cone. Sound quality is very good though and do is the volume ( good efficiency for a small speaker). Bought last summer and still working great. I am very happy, will probably buy another and just swap out the one in the other speaker too. Review: Very Good at a Good Price - I have a set of "History of Music" Book Shelf speakers. Roughly 11x8x4 and look like large books. The drivers started failing, one in each speaker was kicking in and out. These were a exact fit and sound great. I compared the sound Old vs (1 Old & 1 New) vs New. The old worn out speakers sounded brighter but also had some rattling distortion. One old and one new sounded the best but also had the distortion from the old speaker. I ended up using all four, two per speaker and equalized just a bit. The bass and mid range is tight and they handle a full 10 watts easily. I also compared using a frequency sweep where the tweeter used to handle most of the mid-high and all of the high frequencies. The old original 3" speakers started fading around 1000 Hz. These GRS 3FR-4 speakers don't fade till 1400-1500 Hz. The crossover circuit is the same so that means the old speakers cannot reproduce the higher frequencies as efficiently. I have to say these are great speakers, especially for the price. :-) ## Features - Coated paper cone with foam surround for clear sound - Pincushion-shape frame with front gasket - Economical ferrite magnet assembly - Quality GRS construction and 1-year warranty ## Technical Specifications | Specification | Value | |---------------|-------| | ASIN | B00K2ESJZ2 | | Additional Features | Subwoofer | | Antenna Location | Home Theater,Construction | | Audio Driver Type | Dynamic Driver | | Audio Output Mode | Surround | | Best Sellers Rank | #54,651 in Electronics ( See Top 100 in Electronics ) #511 in Car Coaxial Speakers | | Brand | GRS | | Color | Black | | Compatible Devices | Laptop, Personal Computer, Smartphone | | Compatible with Vehicle Type | Car | | Connectivity Protocol | Bluetooth | | Connectivity Technology | Auxiliary | | Control Method | Touch | | Customer Package Type | FFP | | Customer Reviews | 4.3 out of 5 stars 595 Reviews | | Enclosure Material | Foam, Paper, Metal | | Frequency Response | 20000 Hz | | Impedance | 4 Ohms | | Is Waterproof | FALSE | | Item Dimensions D x W x H | 3.2"D x 3.7"W x 2"H | | Item Weight | 0.7 Pounds | | MP3 player | No | | Manufacturer | GRS | | Maximum Range | 15 Meters | | Model Name | 1 | | Model Number | 1 | | Mounting Type | Bar Mount | | Number of Audio Channels | 3.0 | | Number of Items | 1 | | Power Source | Corded Electric | | Speaker Maximum Output Power | 25 Watts | | Speaker Size | 3 Inches | | Speaker Type | Surround Sound | | Specific Uses For Product | Construction, Home Theater | | Subwoofer Connectivity Technology | Wired | | Subwoofer Diameter | 3 Inches | | UPC | 848864015194 | | Unit Count | 1 Count | | Warranty Type | Limited | | Wireless Technology | Bluetooth | | Woofer Diameter | 3 Inches | ## Product Details - **Audio Output Mode:** Surround - **Brand:** GRS - **Connectivity Technology:** Auxiliary - **Frequency Response:** 20000 Hz - **Speaker Maximum Output Power:** 25 Watts ## Images ![GRS 3FR-4 Full Range 3" Speaker Driver 4 Ohm - Image 1](https://m.media-amazon.com/images/I/61jWgSjcbBL.jpg) ## Questions & Answers **Q: What is the exact outside dimension of the speaker frame? I'd like to mount it in an enclosure which allows room for a 3 1/4 inch wide speaker.** A: The front mounting flange of this speaker is basically square, with the four sides of the square being slightly rounded outward. There are four mounting holes, one in each corner of the mounting flange. The distance across the diagonals of the flange (crossing two opposite corner mounting holes) is 3.75 inches. The distance across the widest middle section of the flange ( intersecting the center of speaker cone) is 3.165 inches. Measurements were taken with a dial caliper and are accurate to 1/1000th (0.001) of an inch. So, the speaker will just squeeze into your 3.25" mounting space with only 0.085 (about 3/32") of an inch to spare - assuming you are measuring the 3.25" across the width of a square speaker mounting space and not diagonally across the square space. BTW The depth is 1.7". **Q: Does it comes in pairs or this is just a single speaker ?** A: It's a single speaker. If you'd like a pair, you'll have to order two. Worth the extra effort. Mine sounds great. **Q: whats the wattage/rms of this speaker?** A: Thank you for contacting Parts Express. To follow are Product Specifications for the item. Nominal Diameter3"Power Handling (RMS)10 WattsPower Handling (max)20 WattsImpedance4 ohmsFrequency Response135 to 16,000 HzSensitivity81 dB 1W/1mVoice Coil Diameter0.75"I hope the information is helpful.

They are loud and sound good, however, the speakers that I was replacing were much more crisp and hit the high frequencies better. However, these speakers are very well-built, with a heavy magnet and a high quality cone. Two of these and a tweeter sounds great for small applications. ## Frequently Bought Together - GRS 3FR-4 Full Range 3" Speaker Driver 4 Ohm - OliYin 10pairs JST-XH 2.54mm 1S 2 Pin Balance Plug Lead Socket Male and Female Connector with 22awg 10cm Silicone Wire Cables - Anker Nano USB C Charger Block, 30W PIQ 3.0 Foldable iPhone Charger Fast Charging for iPhone 16/15 Series, Galaxy, iPad, Compatible with MagSafe --- ## Why Shop on Desertcart? - šŸ›’ **Trusted by 1.3+ Million Shoppers** ā€” Serving international shoppers since 2016 - šŸŒ **Shop Globally** ā€” Access 737+ million products across 21 categories - šŸ’° **No Hidden Fees** ā€” All customs, duties, and taxes included in the price - šŸ”„ **15-Day Free Returns** ā€” Hassle-free returns (30 days for PRO members) - šŸ”’ **Secure Payments** ā€” Trusted payment options with buyer protection - ā­ **TrustPilot Rated 4.5/5** ā€” Based on 8,000+ happy customer reviews **Shop now:** [https://www.desertcart.fr/products/11950166-grs-3fr-4-full-range-3-speaker-driver-4-ohm](https://www.desertcart.fr/products/11950166-grs-3fr-4-full-range-3-speaker-driver-4-ohm) --- *Product available on Desertcart France* *Store origin: FR* *Last updated: 2026-07-10*
